The present invention relates to compositions for treating hard surfaces, comprising a water-soluble or water-dispersible compound as component A which is obtainable by reacting: aa) polyalkylenepolyamines, polyamidoamines, polyamidoamines grafted with ethyleneimine, polyether-amines and mixtures of said compounds, as component Aa; ab) if appropriate at least bifunctional crosslinkers which have, as functional group, a halogenhydrin, glycidyl, aziridine or isocyanate unit or a halogen atom, as component Ab; and ac) monoethylenically unsaturated carboxylic acids, salts, esters, amides or nitriles of monoethylenically unsaturated carboxylic acids, chlorocarboxylic acids and/or glycidyl compounds, such as glycidyl acid, glycidylamide or glycidyl esters; and water; to a process for the preparation of a water-soluble or water-dispersible compound, to water-soluble or water-dispersible compounds preparable by the process according to the invention, and to the use of water-soluble or water-dispersible compounds according to the present application in compositions for treating hard surfaces.

Polymer for treating surfaces

There are described azo dyes of the formula ##STR1## where in case a)

Doubled azo dyes

The wet-end coloring of paper with pigments and fixers is carried out by a process in which the pigment and fixer are added simultaneously to the paper pulp to be colored, and the fixer used is a cationic fixer, in an amount of from 0.01 to 3% by weight, based on the dry paper pulp to be colored.

Paper, board, and cardboard having high dry strength are made by adding to the paper stock a dry strength agent which is obtainable by mixing enzymatically digested starch having a viscosity of from 20 to 2,000 mPa.s (measured in 7.5% strength aqueous solution at 45.degree. C.) and a cationic polymer which contains, as typical copolymerized monomers,

Sizing agents for paper are based on finely divided aqueous dispersions of copolymers obtainable by copolymerizing from 40 to 140 parts by weight of a monomer mixture of

Sizing agents for paper based on finely divided aqueous dispersions

Paper and paperboard of high dry strength are produced by adding a dry strength enhancer to the paper stock and dewatering the paper stock with sheet formation by using as the dry strength enhancer a mixture of a cationic polymer which contains as characteristic monomers copolymerized units of

Aqueous dye mixtures for black shades containing as dyes essentially those dyes which have the C.I. number 19,140, 40,000 or 47,035, in the form of the alkanolammonium salt, and also the dyes of the formula I, II and/or III ##STR1## where the cations R.sup.+ are each independently of the others an alkanolammonium cation, a substituted or unsubstituted ammonium cation or an alkali metal cation, and the quantities of the individual dyes are such as to produce a black, are suitable in particular for dyeing paper and leather.

Liquid black dye mixture

Paper, board and cardboard are produced by draining a pulp slurry in the presence of high molecular weight, water-soluble polymers of N-vinylamides as drainage aids, retention agents and flocculants. These polymers are particularly effective in a pulp slurry which has a high content of interfering substances and other phenolic compounds.
